CULICINI 201 Fellzale. Length 3 mm.; wing 2.5 mm. Proboscis very long, some- what enlarged at the apex, dark scaled. Occiput clothed with broad, flat scales, bright metallic violet blue in front and at the side, dark brown and black on the rest. Mesonotum yellowish-brown clothed with fine bronzy-brown scales ; a narrow median line of broad flat, brilliant metallic blue scales extending from near the anterior margin to the scutellum where it broadens into a small patch; on each side in front of the roots of the wings there is a narrow line of metallic blue scales extending forward to about the middle of the mesonotum. Scutellum trilobate, the median lobe very large and clothed with brilliant blue scales, lateral lobes small with brownish scales; each lobe with a tuft of long black bristles. Abdomen short, truncate, with broad, flat, brownish scales which have a bluish iridescence; apices of third, fifth and sixth segments with a median patch of dirty white scales; venter clothed with dirty whitish scales. Wing-scales brown; basal half of fifth vein with pale blue scales and a similar short patch at the root of first. Legs slender, dark brown; apices of femora and tibiae white scaled. Male lzypopygizinz. Side-piece short, a little longer than wide; apical lobes absent; basal lobe short, conical, crowned with two strong spines and several smaller ones. Clasper short, expanded at the middle, constricted before the apex. Tenth sternite apparently absent unless represented by a very thin membrane; the tergite is represented by two stout projections extending forward from beneath the large lobe of the ninth segment. Mesosome stout, heavily chitin- ized, of two lateral plates, each plate with three ventral hooks; the plates are united at their basal ends by a broad band of chitin; apex ends in two stout hooks and several small denticles. The ninth segment is well developed with a pair of large median rectangular lobes extending to near the apex of the mesosome. Larva. Head elongate, longer than wide. Antenna small, spined on one side, a single small hair on basal third; upper and lower head hairs single, stout and thick like heavy spines; anteantennal tuft of four hairs. Abdomen rather small; lateral tufts of the first and second segment long, in threes, nearly obsolete on the other segments; numerous small hairs and tufts scattered over the abdominal segments. Lateral comb of the eighth segment of a row seven to ten teeth on the distal edge of a large, transverse, chitinous plate, single tooth spine-like. Anal segment about as long as wide, completely ringed by the dorsal plate; posterior margin of dorsal plate with a row of very fine spines; dorsal brush a tuft of three hairs on each side; ventral brush well developed, confined behind the dorsal plate,
202 MOSQUITOES OF NORTH AMERICA Air-tube cylindrical, straight, about three times as long as wide; pecten of short evenly spaced teeth, reaching to the tuft; tuft large, multiple, situated just beyond the pecten, before the middle of the tube. This species occurs throughout the eastern United States from the Gulf of Mexico to northern New England. It is rarely taken. URANOTBNIA LOCVII Theobald Uranotmsia Zowii Theobald, Mon. Culic., 2, 339. 1901. Uranotmia continestalis Dyar and Knab. Jour. N.Y. Ent. Sot. 14, 187. 1906. Uranotmia mimta Theobald, Mon. Culic., 4, 559. 1907. Female. Length 2.5 mm.; wing 1.5 mm. Proboscis long, black, enlarged towards the apex. Occiput black, bordered with bluish white scales. Mesonotum yellowish-brown, darker medianly, the median area appearing bluish in certain lights; a black patch in front of wing base with a few bluish scales near its centre. Abdomen black, the third, fifth and sixth segments with lateral, apical silvery patches, bluish in some lights; venter yellowish. Legs black, the apex of the third and all of the fourth and fifth hind tarsal joints white. Wing-scales black, the fourth and fifth veins with a short line of blue scales near their bases. Male laypopygizm. Side-pieces short, conical ; apical lobe absent ; basal lobe a small thickened area on dorsal side of excavation and bears numerous, short, rather stout setae. Clasper short, stout, the apex broad with about eighteen short recurved claws. Mesosome a very complicated structure, composed of two lateral plates with many branches and united dorsally by a broad bridge which bears three pointed median processes. Lobes of ninth tergite broad oval plates, meeting in the middle line. This mosquito occurs in the Gulf States, South America and parts of the West Indies. It bsreeds in small pools and grassy margins of lakes. The adults are not known to bite. GENUS ORTHOPODOMYIA Orthopodomyia Theobald, Entom. 37, 236. 1904.
